Liaison.
Goals Accomplished, 1997-1998.
-
Continue tracking of health problems, both new and updates on previously entered
dogs
-
Educational articles via club publications and the Beardie Health Web
Page
-
Health Research Project for Addison's Disease
-
Health Registries Proposal
Mission Statement for 1998-1999.
-
Health Registries. Work in conjunction with the board to establish these
registries. A proposal was with the board but was tabled.
-
Education.
-
Establish a Bearded Health Foundation to fund research in Addison's disease and
other health problems to be identified in the future.
-
Continue tracking health problems, as done for the last 2 years. Depending on
board action on the proposed motion to close the 1996 health survey, it will be necessary to either renew
that old system or to establish a new system for tracking health problems. This is an effective mechanism
for being alerted to new problems and knowing is what happens to old problems. Until we have no more health
problems of note, we must be dedicated to having a system for tracking health problems.
Beardie health Web Site. Written and maintained by E. Sell for the benefit of Bearded Collie
owners; this is not BCCA sponsored). This web site was initially established in November 1996 as a way to submit
health survey forms and to ask questions about health problems. It became also an educational forum in January
1998. Since my ISP began to provide information in April 1998, the average number of hits per day have increased
from 282 to 513 during the first 3 weeks of September, 1998.
The articles most frequently hit (author name in ()) (a 4 month average) are as
follows:
- Genes (Bell) 85
- Autoimmune1 (Aronson) 80
- Arthritis (Aronson) 77
- Vaccination (on for 1 mo) (Aronson) 77
- Addison's (Lang) 73
- Worms (Aronson) 71
- Old dog (Aronson) 71
- Cryptorchidism (Aronson) 67
- Thyroid, aggression (Aronson) 67
- Heartworm (Sell) 66
The remainder of this report consists of the data from the cumulative health survey for the
years 1996-1998.

* Numbers in parentheses are cases reported in September and owners have not yet
gotten in their health survey forms.
** These diseases are difficult to definitively diagnose at times; some dog's
diagnoses were therefore suspect because all diagnostic criteria had not been met. They may be at some time in the
future.
1 Nail problems included various diagnoses: pemphigus, lupoid onychodystrophy,
infection, unknown. Nail biopsy is needed to establish a diagnosis of lupoid onychodystrophy; bacterial and fungal
cultures are necessary to rule out infection. Sometimes two causes can occur (e.g., infection and lupoid
onychodystrophy).
Cases and Frequency of Addison's Disease
(The dogs in each survey year different, based on
year of birth, sex, and reproductive status)
1992 Health Survey |
18 Addisonian dogs |
804 total dogs |
Frequency of Addison's disease = 2.2% |
|
1996 Health Survey (dogs born after
1989)* |
22 Addisonian dogs |
805 total dogs |
Frequency of Addison's disease = 2.7% |
* There is no difference in frequency of Addison's disease between the two surveys.
An important feature of this table is that the frequency of Addison's disease is not low; the normal dog population
frequency of Addison's disease is reported to be 0.1%. It is also important to know that the two surveys were
designed for different purposes, the forms for reporting were different, and the health chairpersons were
different. The previous health chair provided birth years, sex, and reproductive status of the 92 Addisonian dogs
to me (no owner or dog identification was revealed). I removed any dogs from the 96 Addison's group (for the above
table only) who had the same birth years, sex, and reproductive status as an Addisonian dog in the 92 survey in an
attempt to assure that the calculated frequency of Addison's used different dogs.
Clinical Presentation of Bearded Collies with Addison's Disease (cumulative data for
1996-1998). There were 61 Addisonian dogs with health survey forms; 23 (37.7%) were male and 37 (60.7%) were
female; 1, unidentified sex. At the time of Addison's diagnosis 12 (19.7%) were reproductively intact; 15
(27.3% were neutered males; 25 (45.5%) were spayed females; in 9, reproductive status was not known. There
were 40 (65.5%) living; the others were deceased. The age of onset ranged from 6 months to 11 years, with the
average age at 3.9 years. 27/30 with information on onset age were four years of age or less at time of
Addison's disease. So, this is occurring in relatively young dogs.
Thirty-four owners reported presenting symptoms and/or laboratory work. All 8
who reported lab work had "renal failure" (elevated blood urea nitrogen - BUN, and elevated creatinine). All
except one were reported to have one or more symptoms: poor appetite in 16, vomiting in 12, diarrhea in 11,
weakness in 10, lethargy in 7, sound sensitivity in 6, less than normal activity in 4, weight loss in 3, coat loss
in 3, stress intolerance in 2, discoordinated movements in 2, shivering in 2, depigmentation in 2, and seizures or
aggression, 1 each.
These are non-specific clinical findings, meaning that more than one disease can
cause them. If you have a young Beardie who suddenly becomes ill with a combination of these findings and
your veterinarian diagnoses "renal failure", tell the veterinarian about what is presently known of Addison's in
Bearded Collies. Copy and give him/her a copy of this article. There is a diagnostic test for Addison's
disease - the ACTH stimulation test, in which cortisol levels are drawn before and after injection of
ACTH.

* Cumulative percentage excludes accidental deaths which occurred most often in the
two youngest age groups.
The previous table shows that a quite high proportion of Beardies die before the age
of nine years. Of course, the data are representative only of the population in the survey and should not be
generalized to all Beardies. Even so, is it not worrisome to have 30% dying before the age of nine years? I think
the answer is yes. The next table shows which health problems were responsible for the deaths of these younger
dogs, excluding accidental deaths.

Several points deserve comment. First, autoimmune health problems claim more than 50%
of their deaths before the age of 9 years. If those health problems could be prevented from happening, wouldn't
that be progress? Among the autoimmune problems, 9 were Addison's disease, 3 had more than one A/I problem, and 1
had inflammatory bowel disease. An additional 2 had pancreatic insufficiency (which may or may not be an A/I
disease) and these 2 were not counted as autoimmune problems in the figures above.
The second point is that Addison's disease usually presents as kidney failure in the
first laboratory workup done on the dog who suddenly becomes very ill. This is because of mineral imbalance in
Addison's disease and the resulting dehydration and shock. Addison's disease is probably not a cause for kidney
failure which is chronic and long term before death; if it were, it would have been diagnosed. So, if you have the
misfortune to have a young Beardie die suddenly of kidney failure please ask your veterinarian to perform a
necropsy and have the kidneys and adrenal glands sent for pathology evaluation.
Causes of Death in Other Age Groups.
In the 9-11 year age group (#=43; information available on 39), cause of death
was: cancer (#=18, 42.6%); Addison's (#=5; 12.8%); kidney disease (#=4; 10.3%); cardiac (#=2; 5.1%); 1 each
for anemia, arthritis, liver disease, seizures, stroke, pancreatic insufficiency, accidental, infection. Two
had very rare diagnoses.
In the 12-14 year age group, (#=98); information available on 93), cause of death
was: old age (#=29; 31.2%); cancer (#=24; 25.9%); kidney disease (#=10; 10.8%); stroke suspected (#=6; 6.5%);
cardiac (#=5; 5.4%); arthritis (#=3; 3.2%); rare diagnoses (#=3); Addison's (#=2; 2.2%); accidental (#=2); liver
disease (#=2); one each for colitis, diarrhea, hip dysplasia, infections disease, seizures, pancreatic
insufficiency, multiple autoimmune diseases.
In the > 14 year age group, (#=31), cause of death was: old age (#=20;
64.5%); stroke (#=5; 16.1%); cancer (#=3; 9.7%); kidney disease, 2; Cushing's disease 1.
Types of Cancer in All Age Groups Combined. The number of cases by organ system
are listed below: bone, 12; hemangiosarcoma, 8 (5 in <9 yr group); mammary, 8; 4 each, liver and
abdominal; 2 each, testicular, nasal, liver, stomach, nerves; 1 each, melanoma, leukemia, throat, sweat gland,
mouth, lung, prostate, thyroid and adrenal combined, lymph glands, basal cell, lymphosarcoma, lymphoma, multiple
myeloma; unspecified, 13.
I hope that this information will be useful to you. Elsa Sell, previous BCCA
health chairperson.
